Array Design and Beamforming for Wireless MIMO Systems
Phased array front-ends in MIMO communications systems enable a range of spatial signal processing algorithms including beamforming which are critical to achieving the desired performance of 5G, satellite, airborne, and other modern wireless applications.
In this session, we will introduce techniques to design and evaluate MIMO antenna arrays which can be used in wireless communication systems, including 5G systems. We will look at ways to model, design and synthesize the array geometry, element spacing, subarrays, tapering and the effects of mutual coupling. The session will demonstrate ways to apply the appropriate level of fidelity at each stage of the project. We will also demonstrate techniques to explore architectural trade-offs for beamforming and related spatial signal processing algorithms. These techniques can be used to improve channel capacity and data throughput in multi-user scenarios. They also can be used to identify and eliminate interference sources in shared spectrum environments.
You will learn to:
- Design multi-beam and electronically steerable antennas for massive MIMO and mmWave systems.
- Use antenna arrays to improve the SNR and capacity of a wireless link.
- Send multiple data streams through a scatter-rich channel by using a set of precoding and combining weights derived from the channel matrix.
- Employ hybrid beamforming at the transmit end of a massive MIMO communications system, applicable to both multi-user and single-user systems.
